Our reading
An editorial interpretation.
The speaker responds to continued resistance with mock surprise and a condescending warning about revenge. Calling the determination overdeveloped turns it into a supposed personal defect. The final prediction of trouble makes the rebuke sound almost advisory, even while it dismisses the other person's effort to win.
